"𝐘𝐨𝐮 𝐚𝐫𝐞 𝐦𝐲 𝐬𝐮𝐧𝐬𝐡𝐢𝐧𝐞..." Yushiro X OC Fic (In Progress)

When a demon slayer and an Upper Moon cross paths, there's usually only one outcome- death. But when Yushiro Yamamoto meets naive slayer Hayami Mitsuko, he finds he can use her for information on the demon slayer corps. However, the results of such a strange friendship are more than he bargained for.
